For cheap products, I love this moisturizer. My skin is pretty stable, but can be combination in the winter and summer, this balances it out.
As for homemade stuff, I make a lot of homemade masks. I'm wearing one as I write this that is blended dried rose petals, rose water, and activated charcoal for exfoliant when I wash it off.
I also like using rose water or orange blossom water as a toner, and I keep both in the fridge for cooling in the summer. I like making a super concentrated chamomile tea and keep that in the fridge to use for makeup removal and as a cooling mist when it's really warm.
